I took a chance and tried the KAS Maestro IC's. I won a pair off Audiogon and figured $250 was a fair price for trying a solid silver interconnect. Besides there is a 60 day return policy. I am glad I tried them. There was a significant improvement over the Audioquest Pythons I use. The bass was more extended and smoother with greater detail. The highs were more extended and detailed. Clarity through the entire spectrum also increased. The music was more detached from the speakers and the dynamic range improved. I have ordered two more sets and I'm going to try one of the power cables from KAS. I'm also going to try them as a digital interconnect because I find most cables that sound better as interconnects also perform better as digital interconnects. My main system consists of Infinity Compositions, Krell KAV-250a, Krell 300i (preamp), Classe Dac-1, Genesis Digital Lens, and a McIntosh MLD7020. Speaker cable is Audioquest Clear, Digital interconnects are both Virtual Dynamics Nites (they out perform the Illuminations D-60), preamp to amp are KAS Maestros, and Classe Dac-1 to Digital Lens are Audioquest Pythons XLR. The KAS replaced a set of Pythons from the preamp to amp. I also have a Krell HTS but the Classe DAC-1 out performs the Krell for CD playback. I also use Virtual Dynamics Nites power cables on the Classe & Krell KAV-250a, and a Virtual Dynamics Signature on the preamp. The Virtual Dynamics power cables also provided a tremendous improvement. Hope this helps give useful information about KAS interconnects. I highly recommend them. (The KAS IC's also out performed the Virtual Nites)
